Select options below to build your part number.
Instructions
- Part number format: Frame + Interrupting + Current + Trip + Connectors + Poles.
- Example: T3S080TW-4 = T3 frame, Standard interrupting, 80A, thermal-magnetic, no lugs, 4 pole.
- 3 pole is the default — no suffix is added. Other pole counts add a dash suffix (-1, -2, -4).
- Current rating must not exceed the frame size (e.g., T1/T2 max 100A, T3/Ts3 max 225A).
- Not all interrupting/trip combinations are available for every frame. Refer to the selection guide.
- Factory-installed accessories (auxiliary switch, shunt trip, undervoltage release) are ordered separately.
